Former Bernie Sanders alternate delegate Courtney Rowe joined the Democratic congressional primary for purposes of challenging two-term Rep. Rod Blum (R-Dubuque). Ms. Rowe will oppose state Rep. Abby Finkenauer, who announced her own candidacy in early May. Here again we see a potential Clinton-Sanders style Democratic primary fight emerging but it remains to be seen if Ms. Rowe, who has never previously run for elective office, will be a serious contender. The eastern Iowa 1st District is the most Democratic seat in the Hawkeye State, meaning Rep. Blum can again expect to face serious opposition next year.
